Clearer editor progress and image controls

The editor now shows carousel generation progress directly on the canvas and briefly confirms when a draft is ready to edit. Create inputs also guide new drafts with clearer example prompts.

Slide image editing is more direct. Supported standard slide images can be selected on the canvas, replaced from the media picker, resized where available, or removed from the properties panel without losing the current selection.

Brand identity placeholders are safer by default. Applying a brand profile automatically replaces defaults such as logo, website, and handle placeholders, while custom header and footer text is only overwritten when you choose that option.

Exports and signup activation have fewer interruptions. Free exports no longer require a separate export security challenge, and signup only asks for an extra security check after repeated attempts.

Template generation also keeps explicit template text styling more consistently, including colors, backgrounds, and fonts when those styles are part of the saved template.
